The article analyzes different types of wind turbines to find the most efficient one for specific wind conditions in Poland. By studying wind measurements, researchers identified the best turbine with the lowest sensitivity to wind speed changes and highest energy production. They tested six turbines with power ranging from 2.0 to 2.5 MW and rotor sizes from 82 to 100 m. Turbines with a nominal power of 2 MW were found to be the most effective, while those with 2.3-2.5 MW were less efficient. The study used Weibull density distribution to assess energy efficiency and hourly wind speed distribution. Ultimately, the research pinpointed the turbine that generated the most energy regardless of wind speed variations.
